Computer analysis of cortical evoked potentials following severe head injury.
A combination of several automatically-extracted quantitative features of evoked potentials (EPs) can discriminate between globally good and poor outcomes following severe head injury. Further, a single EP feature, its peak-to-peak variance, can select for the severely disabled survivor from among other poor outcomes, a potentially important distinction for the management of patients suffering severe head trauma.
